LOGGING APPARATUS.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed November 14, 1903. Serial No. 181,205.

To ctZZ whom, it may concern.-

Be it known that we, THOMAS SPENCER MILLER, a citizen of the UnitedStates, and a resident of South Orange, county of Essex, and State ofNew Jersey, and JosEPn H. DICKINSON, a citizen of the United States, anda resident of lWIontclair, county of Essex, and State of New Jersey,have invented a new and useful Improvement in Logging Apparatus, ofwhich the following is a specification.

Our invention relates to log-loading apparatus, and hasparticularapplication to a car adapted to be constructed in such a manner as toenable the bunkers thereof to be adjusted to permit the-empty cars topass beneath the platform of a straddling derrick.

Heretofore to enable the derrick to stand upon the endsof therailway-ties without ntercepting the free passage of the cars beneathits platform it has been considered necessary to provide the derrickwith more or less cumbersome mechanism projecting laterally andbroadening the space required for the accommodation of the derrick.

The object of our present invention is to overcome these difficulties ina more simple and expeditious manner and one which will enable, ifdesired, the use of a derrick structure substantially no wider than thelength of the ordinary railway-ties u on which it rests. This object weaccomp ish by securing the lop-supporting bunkers to the car in suchmanner that their ends may, when unloaded, be moved inboard or towardthe center of the car, thus enabling the width of the car to be reducedto substantially the length of the car-axles. I

The form of mechanism in which this invention may be embodied can bevaried, two forms being below described as examples.

In the accompanying drawings, Figure 1 represents sufficient of aderrick of the class described to illustrate our invention with a carpassing beneath it in end view. Fig. 2 shows in plan view the car indetail. Figs. 3 and {i show modifications.

1 is a railroad-track.

2 isthe tie.

3 is the derrick-platform.

4 and 5 are the supports for the platform resting on the ties onopposite sides of the track.

6, 7, 8, and 9 are respectively the wheels, axles, bolsters, andlongitudinal beams of a logging-car.

10 are the bunkers forcarrying the logs, and 10 is a modified bunker. Inthe construction shown in Figs. 1, 2, and 3 each of the bunkers 10 ispivoted at its'center to the car-frame by the pin 11, so as to becapable of swinging from the transverse or log-carrying position (shownin dotted lines in Fig. 2 and in full lines in Fig. 3) into the diagonalposition. (Shown in Figs. 1 and 2 in full lines.)

As the car in unloaded condition is passed beneath the derrick-platformthe bunkers 10 are in diagonal or inboard position; but when theplatform is passed and the car is about to be loaded with logs thebunkers are moved into the transverse position. In this manner the caris adapted to receive a full-width load of logs and at the same time isadapted to be narrowed by the movement of its bunkers to such a width asto permit it to pass readily between the side supports of thederrick-platform.

In the modification shown in Fig. 4 the bunkers instead of being pivotedare formed of parts 1O and 10*, mounted so as to telescope within thepart 10"., thereby possessing substantially the same inboard movingfeature as though pivoted.

In Fig. 3 the gage of the car passing between the platform-supports isstill further reduced by transferring the axle-bearings 12 from theposition that they occupy in the other figures outside of the wheels topositions inside of the wheels, thus correspondingly reducing the lengthof the axles.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent" The combination with a loading-car, oflogbunkers thereon, each log-bunker comprising a plurality oftelescoping members having inboard movement whereby said car may bepassed through a derrick or the like straddling the track.

In testimony whereof we have hereunto signed our names in the presenceof two subscribing witnesses.
